5 days to save the world, 4 days to save her family, 3 hours to find the world’s most dangerous double-agent. James Patterson’s biggest ticking time bomb of a thriller is the ultimate test for a young CIA agent who’s been handed an impossible mission. Agent Amy Cornwall excels at working from the shadows–until a botched field operation reveals dark dealings between her bosses and an informant. And a hidden plot by a terrorist genius that could kill thousands of Americans. Among them: her husband and daughter.

She has to go dark. The Division wants to erase her. And they know every detail about her identity, her history, and her family.

Agent Cornwall’s countdown has begun.
